colored Metal material
Not sure if I am understanding correctly. Also not sure what render engine you are using. If its cycles I recommend downloading 2.79 (if you don't have it already) and use the Principled BSDF shader with the Metallic set to 1 and play with the roughness value until you are happy with the results. 

Also keep in mind you need a light source to actually reflect the light. I used an HDRI in this image but you can just use a plane mesh and put an emission shader on it. Then position it how you like best.
